George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35),
and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money.
15 - 9 + 2.65 + 1.35 + 2(1.74)
Use the order of operations to simplify this expression.

Answer:
Yes, he has enough money and your simplified answer is below. If I'm wrong correct me or give me a comment.
Step-by-step explanation:
15 - 9 + 2.65 + 1.35 + 2(1.74) Multiply first.
15 - 9 + 2.65 + 1.35 + 3.48 Then just add or subtract from the left to the right
6 + 2.65 + 1.35 + 3.48
8.65 + 1.35 + 3.48
10 + 3.48
13.48 would be the simplified answer.

Answer:
L = 13 m W = 11 m
Step-by-step explanation:
L = W + 2
area = L x W
143 = (W+2) * W
143 = W^2 + 2w
W^2 + 2W - 143 = 0
Use Quadratic Formula (a = 1 b = 2 c = - 143)
to find W = 11 m then L = 13

Answer:
m∠BJK = 146
m∠IJB = 26
Step-by-step explanation:
m∠BJK + m∠IJB = m∠IJK
<em>146 </em>+2x + 2x +<em>26</em> = 172
<em> 172 </em> + 4x = 172
4x = 172 -172 = 0
x = 0
m∠BJK = 146
m∠IJB = 26
